Description

Technical Field

Background Art

[0002] The existing broken strand repair robots for power transmission lines, after completing the task of pulling back the broken strands, mainly repair and reinforce the faulty lines by punching clips or wrapping repair strips or pre-twisted protective wires. However, the clips are not strong enough, the reinforcement effect is poor and the reliability is low. In order to achieve the repair strength, the required repair strips and pre-twisted wires are relatively long. If the broken strand repair robots for power transmission lines are used to perform automatic reinforcement actions at high altitudes, the required space size is relatively large. Due to the restrictions on the space volume and weight of the mechanism in the high-altitude working environment, the battery life of the rechargeable batteries that can be equipped is relatively short.
